Fighting humidity in a 5th Wheel

Fighting humidity in a 5th Wheel

Humidity can be arguably one of the worst problems to overcome when living full-time, or camping in a 5th wheel or other RV. Over here in Washington state The 5th Wheel 5 live full-time in A RAIN FOREST! Now when most people hear Rain Forest they think of the amazon (and not the awesome one with one day shipping)! However those of us from the Pacific Northwest know that Rain Forests are alive and well up here. The last rain storm we had resulted in a flood that was about 6 inches deep at its crest and made our tiny house, an Island Oasis according to our oldest son.

**Side Note, it’s extremely difficult to explain to three boys why we can’t go fishing outside of the bedroom windows!**

The three most common reasons for humidity and condensation on the windows (and walls) of a 5th wheel is due from cooking, showering, and yes, even breathing. Living with 5 people in a 40 foot 5th wheel is no exception to that last one. We quickly learned we needed to get a handle on this before the water started to destroy our lifestyle due to mold, mildew, and rot.

We tried a few different options from “Damp-Raid” buckets, to opening windows, and turning up the heat but the most energy efficient and easiest option for us ended up being a 30 Pint Dehumidifier from Whynter. Coming in at just under $180 it was an option that was middle of the road for price with the most pint payout. To be honest, I thought it might have been overkill but boy oh boy was I wrong! With comfort settings from 35% humidity to 80% and even a pre-programed “comfort” mode that will adjust the humidity based on temperature, this machine is a real workhorse. In only 2 hours of initial set up our windows were dry, and the humidity dropped from 76% down to 50%. And filling the holding tank halfway! image2

We have now found a happy zone of 45 percent humidity that keeps our house dry without feeling like a desert. Our tank needs to be emptied once every day and a half and has a safety shut-off if it is forgotten.

So, now that the review has been written, lets get down to the nitty gritty.


Quite: Seriously, its a very low hum that is not distracting and not noticeable during conversations

Affordable Quality: For the price, this unit can’t be beat! Higher capacity for the price and great reviews made me more prone to try this in a 5th wheel than other models. I haven’t been disappointed.

Design: (See Photo Below) While I did read the instructions, this machine is very user friendly, the buttons are all labeled and self explanatory. image3



The airflow: (See Photo below) This is a double edged sword as far as I’m concerned. Because this unit gets so much moisture out of the air, it also ends up blowing air around, this air is “dry” and can feel cold. At night, if the air is blowing on my legs, I’ll want pants or a blanket. The nicer part is that the air blows out of the side so simply turning the unit around will solve the problem. Overall with 2 months of use, I have been very pleased. image1
